1. Which of the following is an example of a prepositional phrase?

Correct answer: A

Rationale: The correct answer is A: 'After the game.' A prepositional phrase consists of a preposition and its object, describing a relationship in time, location, or direction. In this case, 'After' is the preposition, and 'the game' is its object, making it a prepositional phrase. Choices B, C, and D do not contain prepositional phrases. Choice B, 'Running fast,' is a gerund phrase with an adverb modifying a verb. Choice C, 'She sings,' is a subject-verb sentence construction. Choice D, 'Can you help me?' is an interrogative sentence asking for assistance.

2. Mandy can buy 4 containers of yogurt and 3 boxes of crackers for $9.55. She can buy 2 containers of yogurt and 2 boxes of crackers for $5.90. How much does one box of crackers cost?

Correct answer: C

Rationale: To solve this problem, we can set up a system of equations. Let the cost of one container of yogurt be y and the cost of one box of crackers be c. From the first scenario, we have 4y + 3c = 9.55. From the second scenario, we have 2y + 2c = 5.90. Solving these equations simultaneously, we find that c = $2.25. Therefore, one box of crackers costs $2.25. Choice A, $1.75, is incorrect because it does not satisfy the given conditions in the system of equations. Choice B, $2.00, is incorrect as it does not match the calculated solution. Choice D, $2.50, is incorrect as it does not align with the calculated value for one box of crackers.

3. What is the unit of measurement for power?

Correct answer: C

Rationale: Power is the rate at which work is done or energy is transferred. The unit of measurement for power is the watt (W), named after James Watt, the inventor of the steam engine. The watt is defined as one joule per second, where a joule (J) is the unit of energy. Choice A, Joule (J), is incorrect because a joule is a unit of energy, not power. Choice B, Newton (N), is incorrect as a Newton is a unit of force, not power. Choice D, Kilogram-meter (kg·m), is incorrect as it represents a unit of torque, not power. Therefore, the correct answer is C: Watt (W).

4. What is the name of the cartilage flap that covers the trachea during swallowing, preventing food from entering the airway?

Correct answer: A

Rationale: The correct answer is A: Epiglottis. The epiglottis is a cartilage flap located at the base of the tongue that covers the trachea during swallowing. Its primary function is to prevent food and liquids from entering the airway and instead directs them towards the esophagus. The glottis (choice B) refers to the space between the vocal cords in the larynx. The larynx (choice C) is the voice box containing the vocal cords responsible for phonation. The pharynx (choice D) is the throat region connecting the mouth and the esophagus, playing a role in both digestion and respiration.

5. Microfilaments and microtubules are both components of the cytoskeleton, but they have different functions. Which of these describes microfilaments?

Correct answer: A

Rationale: Microfilaments are thin, solid rods made of the protein actin and are primarily responsible for providing structural support to the cell and determining its shape. While they also play a role in cell movement, their main function is related to maintaining the structural integrity of the cell. Choice B, 'Facilitate cell movement and contraction,' describes microtubules, which are responsible for facilitating cell movement, providing structural support, and aiding in cell division. Choice C, 'Form the mitotic spindle during cell division,' specifically refers to the function of microtubules in forming the mitotic spindle. Choice D, 'Transport materials within the cell,' is characteristic of microtubules that are involved in intracellular transport of organelles and materials within the cell.
